by OffDelay or if it shall give a pulse with duration set by PulseTime. Note that for pulsed
operation and that the inputs are connected in an OR-function, a new pulse will only be
given on the output if all related inputs are reset and then one is activated again. For steady
operation the OffDelay will start when all related inputs have reset. Detailed logical
diagram is shown in figure

Output signals from TMAGGIO are typically connected to other logic blocks or directly
to output contacts in the IED. When used for direct tripping of the circuit breaker(s) the
pulse time delay shall be set to approximately 0.150 seconds in order to obtain satisfactory
minimum duration of the trip pulse to the circuit breaker trip coils.
